Abstract

The Harris Greenstone Belt in the central Gawler Craton of South Australia
has potential for Archaean Ni-Cu-PGE sulphide and Archaean-Proterozoic
lode-Au mineralising systems. This map is a preliminary interpretation of the
Precambrian basement geology based on aeromagnetics, gravity, and diamond
drilling. It highlights the extensive distribution of poorly exposed Archaean
komatiites and associated rocks (green) that have a strike extent of at least
300 km. The regional pattern of linear komatiitic sequences associated with
ovoid granitic plutons and province-wide shear systems, is very similar to the
economically important Eastern Goldfields Province in the Yilgarn Craton,
Western Australia.
